Definitions
- This invention refers to a collapsible tube for car door handles, that presents the peculiarity that it offers a system to fix the car door handles, that prevents serious injuries to the passengers, in case of inner deformation due to side impacts on the vehicle.
- door handles are mounted with passing tubes fixed on the inner plate of the door.
- the invention offers a simple technical solution based on the design of a collapsible tube or, in other words, a tube that automatically reduces its length and rigidity deforming itself in the direction of application of the impact force.
- the door handle itself is arranged as a bridge between two of these tubes fixed perpendicularly to the inner plate of the door.
- the tubular wall incorporates a plurality of longitudinal grooves that practically occupy the whole length of the relevant tube, being such grooves uniformly distributed in an angular direction.
- the end of the tubes, with which the fixing of the handle is produced, is closed and presents a small orifice to enable the fixing screw to pass through.
- the opposite end of these tubes is extended in a wing that conforms the handle.
- These tubes preferably present a slightly trunco-conical configuration, although their section can also be polygonal, and also have'a slight conicity that opens towards the joint with the wing.
- the tubular wall has a longitudinal section that decreases from both ends towards a quasi-central point, thereby forming an annular weakening line located at the central part of the tube and precisely through it the deformation starts, opening the branches or arms formed as a consequence of the existence of the longitudinal grooves.
- Figure 1 It is a schematic longitudinal view, of a car door handle, partially shown, that joins to the metallic structure of the door by means of a pair of tubes, following a conventional arrangement.
- Figure 2 It is an elevation view, of one of the collapsible tubes for fixing the door handle, in accordance with the invention.
- Figure 3. It is a plan view of figure 2.
- Figure 4. It is a section from the A-A cutline of figure 3.
- Figure 5 It is a section from the B-B cutline of figure 2.
- Figure 6 It is a section similar to figure 5, although in this case it shows a polygonal configuration of the collapsible tube.
- Figure 7 It is a schematic view that. shows the deformation of the same tube of figure 2, as a consequence of the impact.
- figure 1 it is referenced in general under number 1 the handle of one of the doors of the car, which joins to the inner plate 2 of the metallic structure of the door, through the passing tubes 3.
- the reference 4 indicates the outer plate of the car, which is initially deformed as a consequence of a side impact indicated by means of arrows.
- the fixing of the handle 1 to the inner plate of the door 2 is made by means of screws passing through the axial hollow space of the relevant tube 3, pressing its head against the ring-shaped wing formed at the relevant end of such tube 3, since its base is closed and incorporates a central hole 5.
- These tubes 3, owing to their conventional structure, have the risk of injuring the passengers of the car, after a side impact, since they cannot be deformed and are not collapsible.
- FIG 4 it can be seen how the tubular wall of the collapsible tube 7 shortens towards the central part where it presents a minimum section, thus materializing a ring-shaped weakening line, referenced under number 8.
- the deformation of the tube 7 begins precisely at such central line 8, as shown in figure 7.
- the longitudinal grooves 6 conform an equal number of arms 9 that bend at their central area at the time of the impact, reducing the shock on the body of the passenger of the vehicle.
- the polygonal collapsible tube has been referenced under reference 7'.

Abstract
Description
Claims (2)
- COLLAPSIBLE TUBE FOR CAR DOOR HANDLES, especially designed to offer a fixing system for the handle, that prevents injuries caused by side impacts on the vehicle, since it automatically reduces its length and rigidity by deforming itself following the direction of the force of the impact, characterized in that it consists of a tubular piece (7, 7') with a slight conicity closed at its smaller base where it incorporates a hole (5) for a screw that fixes it to the inner plate of the door, said tubular piece (7, 7') incorporating longitudinal grooves (6) uniformly distributed in an angular direction, reaching the end where it is fixed to the wing that constitutes the door handle (1) and that joins this tubular piece (7, 7') to another similar and close one.
- COLLAPSIBLE TUBE FOR CAR DOOR HANDLES, according to claim 1, characterized in that the tubular wall of the tubular piece has a longitudinal cross-section section that decreases from both ends towards a quasi-central point thus forming a ring-shaped weakening line (8).
